As multimedia container format, MKV was developed with the intention to serve as a universal format for storing common multimedia content like movies or TV shows. MKV can hold unlimited number of audio, video, or subtitle files into a single file even if these files adopt a different type of encoding. For instance, you could have a MKV file using H.264 for video and something like MP3 or AAC for audio.

MKV container files have several advanced key features, including fast seeking, chapter, menu, and metadata support, different selectable audio and video streams, online streaming compatibility, subtitle (hard-coded and soft-coded) support, and error recovery (allows for playback of corrupted files). The container itself also supports almost any audio and video format, which makes it highly adaptive and easy to use.
